Title: Detecting apparatus for knocking of internal combustion engine
Inventor: KANOU SHIYOUJI
IPC: G01M15/00
Filed: 1989-08-14
Abstract: PURPOSE:To reduce the circuit scale and cost of an apparatus and to correctly detect knocking by providing a means for setting the slice level at a value corresponding to the running state of an engine. CONSTITUTION:A knocking signal output from a knocking sensor 1 is input to an amplifier 2, and the knocking signal output from the amplifier 2 is input to a comparator 3. On the other hand, a slice level setting means provided in a microcomputer (CPU) 4 sets the slice level to a value corresponding to the running state of an engine every time an ignition signal is output from a crank angle sensor. A digital signal of the data of the slice level stored in the CPU 4 is input to a D/A converter 6. An analog signal obtained through D/A conversion of the slice level is input to the comparator 3. The comparator 3 compares the knocking signal with the analog signal of the slice level, and accordingly the presence or absence of knocking is judged by a knocking judging means on the basis of the comparing result.

Abstract: PURPOSE:To obtain an optimum line resistance correction value by employing a line resistance correction value measuring equipment which detects loss of a sudden change in a current and of current flowing caused by varying a variable resistor and a variable power supply and records the resistance of the variable resistor and the voltage of the variable power supply. CONSTITUTION:When a resistance of a variable resistor RV 10 in a line resistance correction value measuring equipment 9 is adjusted to be gradually low, a starting current of a start signal reception circuit 5 is gradually increased, the starting current reaches a sensing value of a relay 8 of the start signal reception circuit 5 to drive a relay C8, then a break contact C7 opens the circuit. Then the starting current flowing between the line resistance correction value measuring equipment 9 and the start signal reception circuit 5 is changed momentarily. The current change is a current change when a resistance of a resistor RR 6 is added and it is detected by a current monitor circuit 11 of the line resistance correction value measuring equipment 9 and the resistance of the variable resistor RV 10 is read by the current monitor circuit 11. Thus, an optimum line resistance correction value is obtained.

IPC: H04N3/00
Filed: 1986-09-04
Abstract: PURPOSE:To prevent a horizontal deflection signal from developing a non-periodical part and the excessive load imposed on a horizontal output transistor by obtaining a vertical synchronizing pulse whose phase is modulated so that the start timing of a field scan is synchronized with the prescribed phase of a horizontal synchronizing signal when one field signal is scanning twice to display it. CONSTITUTION:A quick horizontal synchronizing signal 2HD is supplied to a shift register 271 and a selector 272. A clock 4fH is supplied to the shift register 271 and a shift register 274. The vertical synchronizing signal VD is supplied to a half frequency divider 273, and its output signal VD-a is supplied to the shift register 274, shifted by the clock 4fH, turns out to be an output signal VD-b and supplied to the control terminal of the selector 272. According as a control terminal C is at a low or high level, a phase modulation vertical pulse generator circuit selects the signal of an input terminal X or the one of an input terminal Y, and derives it. As a result a phase modulation vertical pulse PCVD comes to have a pulse waveform with a modulated phase. If, with the aid of such a phase modulation vertical pulse PCVD, a vertical deflection signal with a frequency twice a normal one is generated, the horizontal defection signal never develops the non-periodical part.

Abstract: PURPOSE:To accomplish accurate photometry by arraying respective sensors in such a relation that relative output difference between adjacent sensors becomes minimum concerning spectrum sensors in a photometric device in forming an image by an electrophotographic color copying machine, etc. CONSTITUTION:In the case of detecting light spectrum, which passes an optical system(for example, a diffusion plate 25) from a light emitting source, by the respective spectrum sensor groups 34-39 constituted on the same chip(the same surface), the respective spectrum sensors are arrayed in such a relation that the multiplied value(=relative output) of a certain light spectrum intensity by the sensitivity of a light receiving sensor having light receiving sensitivity to the spectrum becomes minimum as the relative output difference between the adjacent sensors in the respective spectrum sensors. Since the difference of relative output obtained by the intensity of light received from the light emitting source by each light receiving sensor and the sensitivity of the sensor is small even if the adjacent light receiving sensors receive the influence of leaked light each other, S/N by mutual intervention can be almost equally distributed and miscellaneous light has equal influence on a true light receiving signal, thereby accomplishing the accurate photometry.
